Lazer O2 Helmet: Quick Review- by Guitar Ted
Some months ago now, I was sent over a Lazer O2 helmet for test/review. The helmet is made by Lazer Sport, which has a long history in making helmets for cycling, snow sports, and eyewear as well. The O2 model is best known as a road helmet, but this particular model is also geared towards mountain biking, with its removable visor that is included.

Tech Intro: The O2 is loaded with the latest helmet technology, and a unique fit system.
-“Feather Lite“- weighs 280gm (Uni-size)
-“RBS” Rigidity Brace System: In molded reinforcement structure to improve impact resistance and guaranteeing higher safety. (On lower sides and back of O2 model)
-Reflective: Extra reflective features to increase visibility and safety.
-Rollsys® system: Turning the thumb wheel on the top of the helmet activates the Rollsys System which cradles the head completely for improved fit and rider safety.
-Certification: The Lazer O2 is certified by CE – CPSC – AS
-Sizes: The O2 uses the “Uni-size” sizing system provided for by the Rollsys which is from 53-61cm and XL
-Optional “Aeroshell”: The O2, (and some other Lazer models), have an optional, snap on plastic shell which can be used to protect from rain, snow, or to get an aerodynamic advantage. (I’ll have a word on this later.)
Lazer O2 helmets retail anywhere from $90.00 USD to $120.00 USD depending where you look.
Obviously, the Rollsys system is a very unique take on helmet fitting. It was something I had heard about before from other riders and I had heard good things. It essentially works much like the systems used in shoes where a flexible wire is drawn up, in this case by the top mounted cylindrical wheel, and that in turn theoretically tightens around your head in an even manner.
Having a “big melon“, as I do, it is hard to find helmets to fit, and fit well. My head measures 62.7cm around, and it is more egg shaped than it is round. Clearly I needed the XL O2 helmet, and this is what I received to test. The helmet also shipped with the included visor and the optional Aeroshell attachment.
The Fit: The O2 went on okay and I was able to use the Rollsys to tighten the lid to my head almost where it would have fit perfectly. As I said, the head I have is more of an egg shape. Clearly the Lazer O2 was meant for a rounder head shape than mine. It wasn’t a bad fit, but it always rested on the center of my forehead and the back of my head, leaving it to be possible to rock the helmet side to side a bit, even at the tightest Rollsys setting. Kudos to the design though, as it never put excessive pressure on the points where it did contact my head. So- it wasn’t a “perfect” fit, but it was serviceable, so I used it for a time on all my rides.
Ride Testing: The venting system on the O2 is impressively airy and I could feel air flowing over my head as I rode. No doubt this would be a cooler helmet than others I have at my disposal. It also was definitely a light helmet, and that was appreciated since it didn’t ever distract me in that manner. I never really felt any discomfort due to the fit, but the helmet would leave a nice red mark right smack dab in the middle of my forehead after using it. Not a good thing amongst friends with sarcastic senses of humor. That said, it was more of an issue to me since I like to wear a cycling hat under my helmet, and with the way this fit, that was uncomfortable. No cycling hat- it wasn’t a big deal.
The Aeroshell attachment never really worked out. I was possibly sent an Aeroshell meant for the smaller sized helmet shell, which I believe to be the case, since there was no way it was going to snap over the O2 I had. In fact, it began to tear when I did attempt to install it. I imagine a proper fitting Aeroshell might be a cool accessory, but since it didn’t work out for me to try it out, I will leave it at this.
Conclusions: There is no doubt that the Lazer O2 is a light, airy, well made helmet with a very effective fit system in the Rollsys. However, if you are of the “egg shaped” head variety, you may find the fit wanting a bit. Those who fit fine in Giro helmets will love the Lazer O2. Those- like me- who find Bell helmets to be heaven on the head, should maybe look elsewhere. Note: I did get a chance to try on a Lazer Helium at a shop, and it was different than the O2. Those with “large noggins” may want to look at that Lazer model instead, which is offered in an XXL size. It also is made with a Rigidity Brace System that covers more than an O2 does, and also has the optional Aeroshell attachment.
Fit of contact points on a bicycle and clothing and accessories is a highly personal thing, so please take these review comments in context. I know several folks that love Lazer helmets and they perform and protect at a very high level. So in the final assessment for myself, I found the Lazer fit to be sub-optimal for my head. We are blessed to have several choices for these types of items as riders, so finding a perfect fit isn’t impossible, (like it was for myself in 1992, for instance), and my “perfect fit” just doesn’t happen to be this Lazer O2. But it might just be for you, and I highly recommend this helmet if the fit does work for you.
Note: Lazer sent over the O2 helmet at no charge for test/review. I was not paid, nor bribed, for this review. I strive to give my honest thoughts and opinions throughout.
